Question

We can use the
to measure the acidity or basicity of a solution.

Answer 1

We can use the PH scale to measure the acidity or basicity of a solution.

Answer 2

Scientists use the pH scale to measure how basic or how acidic a solution is. If a solution is measured at a 7 on the pH scale, the solution is neutral. Any solution that is measured less than 7 is more acidic, while any solution measured more than 7 is is more basic.
